Dead Pixel Fixer
Complexity: Easy | Time: 5 min
Dead pixels are small dots on your screen that remain stuck on a single colour or do not display anything at all. They can appear as black, white, or coloured spots and are most noticeable on solid backgrounds.
This guide will help you identify whether you have a dead or stuck pixel and walk you through methods that may help resolve the issue.
What is the Difference between a Dead Pixel and a Stuck Pixel?
A dead pixel is a pixel that no longer lights up and typically appears as a black dot on the screen.
A stuck pixel is slightly different — it remains fixed on a single colour (such as red, green, blue, or white) and may sometimes be recoverable.
Why Should I Check for Dead Pixels?
You may need to address dead pixels if you experience:
• Small black, white, or coloured dots that do not change
• Pixels that remain stuck on one colour
• Visible spots on the screen during normal use
• Distractions when viewing images, videos, or games
These issues are usually caused by pixels not functioning correctly or becoming stuck. It is important to differentiate between the two, so that we can take the appropriate next steps.
Important Notes
• Dead pixels (black dots) are usually permanent
• Stuck pixels are more likely to be fixable
• Avoid applying excessive pressure to the screen
• Results may vary depending on the panel type
Steps to Fix Dead or Stuck Pixels
Confirm the Pixel Issue
• Display a solid colour background (black, white, red, green, blue) to identify the affected pixel.
• Power off the display before attempting any physical method.
Set the Resolution to the Recommend Option
• Choose the option marked (Recommended)
• This is the native resolution of your monitor
Apply Gentle Pressure (Optional)
• Using a soft cloth, lightly press the area where the pixel is located
• Turn the monitor back on while maintaining light pressure, then release
Use a Pixel Fixing Tool
• Run a dead pixel fixer tool such as Displaytech Dead-Pixel Check that rapidly cycles colours over the affected area
• Leave the tool running for 10–30 minutes, or longer if needed
Check if the Pixel has Recovered
• Re-test using solid colour backgrounds.
• Stuck pixels may require multiple attempts to resolve.
What's Next?
After checking for dead pixels and using the tool to help fix any stuck pixels, see if the problem is now resolved and your screen returns to normal.
